Abstract
Disclosed are new zwitterionic compounds having a bridge moiety, an electron accepter moiety, and an electron donor moiety. The bridge moiety is covalently bonded to both the electron accepter moiety and to the electron donor moiety. The bridge moiety includes one selected from xanthene and thioxanthene, and the accepter moiety includes a pyridinium moiety, and the donor moiety includes a malononitrile moiety.
Claims9
